Deck: A new security report reveals that dozens of popular blockchains have code enabling asset freezing, challenging the notion that crypto is fully in your control.
Cryptocurrency is often touted as money you control exclusively — no banks, no middlemen. But a recent security analysis of 166 blockchain networks turns this idea upside down. The report found that at least 35 blockchains include code that allows freezing or locking user assets without their consent. This finding raises critical questions about decentralization, user control, and risks for crypto investors. In this article, you’ll learn which chains are affected, how this frozen-asset mechanism works, and what it means for your crypto holdings.
The Truth Behind Crypto Control: Asset Freezing Exists
A comprehensive security team analyzed 166 blockchain platforms. They uncovered:
- 16 blockchains with confirmed ability to freeze or lock user funds.
- 19 more with potential freezing capabilities embedded in their code.
This means over 20% of these networks can restrict access to your cryptocurrency, either directly or as a technical possibility. Notably, these aren't fringe or little-known blockchains — this includes prominent ones like the BNB Chain (Binance Smart Chain), VCHIN, Aptos, and SUI.
How Does Freezing Work?
Typically, blockchains are expected to have permissionless transactions — your crypto, your rules. However, the code in these blockchains allows certain parties, often validators or foundation developers maintaining the network, to "freeze" specific addresses. Once frozen:
- You cannot send your tokens elsewhere.
- You cannot withdraw them.
- Your assets remain locked until (if ever) unfrozen.
This usually happens without a transaction needing your approval.
Why Does This Matter for Investors?
The long-held belief is that owning cryptocurrency means having complete control over your assets at any time. But if the network code allows freezing:
- Your funds could be locked for reasons beyond your control.
- This could happen due to legal orders, security threats, or even errors.
- Your assets' liquidity and usability become uncertain.
Noteworthy: Binance Smart Chain (BNB Chain)
The report highlighted BNB Chain specifically for having freezing capabilities. This is meaningful because BNB Chain hosts millions of users and thousands of tokens. Investor trust hinges on transparency around when and how such controls can be exercised.
Data Callout: Over 20% of Chains Can Freeze Assets
Out of 166 blockchains examined, 35 have either confirmed or potential asset freezing code — that's 21% of networks. This could expose a significant portion of crypto investors to unexpected access restrictions.
Risks: What Could Go Wrong?
- Centralization Risks: The entities controlling freeze functions could act against user interests.
- Legal and Regulatory Actions: Governments might pressure foundations to freeze assets.
- Technical Glitches or Exploits: Bugs could unjustly lock funds.
- Lack of Transparency: Many users remain unaware their crypto can be frozen.
Investors must weigh these risks against the benefits of transacting on "permissioned" blockchains.
Answer Box: Can My Cryptocurrency Be Frozen Without My Permission?
Yes. Some blockchains have built-in codes that let validators or network foundations freeze your crypto assets without your approval. This means your tokens can become temporarily or permanently inaccessible, restricting your ability to transfer or withdraw them.
Actionable Summary
- Over 20% of blockchains analyzed have freeze or lock code affecting user funds.
- Major chains like BNB Chain (Binance Smart Chain), Aptos, and SUI possess this capability.
- The freeze function is controlled by validators or foundations, not the individual owner.
- This affects the fundamental promise of "self-custody" and unrestricted control.
- Understand the terms and network policies before investing or holding assets long-term.
Stay informed about how different blockchains handle asset control can save your investment. The landscape is evolving fast, and what held true yesterday might change tomorrow.

FAQ
Q1: Which popular blockchains have freezing capabilities?
A1: BNB Chain, VCHIN, Aptos, and SUI are among the well-known blockchains with confirmed or potential asset freezing code.
Q2: Who can freeze assets on these blockchains?
A2: Typically network validators or foundation teams operating or maintaining the blockchain have this power.
Q3: Does freezing mean my crypto is stolen?
A3: No, frozen assets remain in your wallet but cannot be moved. It's a form of restricted access, not theft.
Q4: Is asset freezing common in all cryptocurrencies?
A4: No. Many networks like Bitcoin and Ethereum have no known freeze capabilities; this risk is mostly in certain chains.
Q5: How can I protect myself from unexpected freezes?
A5: Research the blockchain’s policies before investing, diversify holdings, and use hardware wallets where possible.
